Equivalent Fractions on the Multiplication Matrix

Equivalent Fractions on the Multiplication Matrix

I’d been staring at equivalent fractions for eons and never knew it. Check out this multiplication matrix filled with them! Way cool!

Starting simply, look at the first two rows in the upper left.  The number in the first row (numberator) is ‘1’ and the number in the second row (denominator) is ‘2’.  Those numbers represent the fraction 1/2.  All the numbers in the two rows to the right reflect the equivalent fractions.

This works for any two numbers picked no matter where on the chart.  The numbers to the left and right will always be equivalent fractions.

You can even choose a number from, say row 5, and the second number directly underneath from row 8.  Equivalent fractions will be those numbers in row 5 and 8, to the left and right.
